WILLIAM: BARTHOLOMEW, OF CHICAGO, ILLINOIS, ASSIGNOR- TO TROY LAUNDRYMACHINERY COMPANY, LIMITED, OF CHICAGO, ILLINOIS, A. CORPORATION OF NEWYORK.

SCOOP WASHING-CYLINDER.

To all whom it may concern lie it known that I, W ILLIAM BARTIIOLO- new,a citizen of the United States, residing at Chicago, county of Cook,State of Illinois, have invented certain new and useful a novelconstruction of'cylindcr for washing and other similar machines having asense of buckets mergingiuto rubbing ribs disposed intermediate ofsuccessive buckets of the series, and further to form the edges of theopenings of the buckets with one of said edges straight and the othercurved, the ends of the openings being formed on curved lines andextending out the plane of the body of the plate. 7

Other and further objects and advantages of the invention will behereinafterset forth and the novel features thereof defined by theappended claims.

In the drawings-Figure l is a detail perspective of a portion of acylinder formed in accordzmce with this invention; Fig. 2 is an enlargedsection extending longitudinally of the buckets; Fig. 8 is a similarsection extending transversely of the buckets; Fig. it is a plan of theinner face of the plate having portions embossed to form buckets; Fig.is a similar View of the slotted plate before the embossing action; andFig. (3 is a detail of the completed plate formed as a cylinder.

Like numerals of reference refer to like parts in the several figures ofthe drawings.

For the purpose of illustration, this invention is shown in connectionwith a washing machine but is equally applicable to a dryin g tumblerand dyeing and similar machines in which a cylinder is used having aseries of apertures with buckets disposed at one side thereof tointroduce and discharge liquid from the cylinder in a succession ofstreams.

The numeral 10 indicates a metallic plate which is curved into the formof a cylinder and supported at each end by the heads 11 arrying thetrunnions 12. The cylinder Specification of Letters Patent.

plate 10 is formedwith a continuous series of openings 13 disposed in asingle circumferentialline, the boundaries thereof being mergedinto eachother forming intermediate rubbing'ribs 14 between successive openingshavingconvened rubbing faces. At one side of each opening, the body ofthe plate is embossed or swaged outward to form a bucket 15 having afree edge 16 curved transversely and longitudinally. The opposite edgeof the openingilil is formed with an outwardly curved flange 17extending beyondthe plane of the plate 10, the edge of this flange beingstraight relative to the curved edge 16 of the bucket, as shown at 18 inFigs. Qand 6. To prevent the collection and holding of lint or othermaterial, the ends of" the opening 13, where the walls of the bucketloand the flange 17 merge, are curved as shown at 19. The base of thebucket 15 and flange 1'? where they are mergedoutward from the rubbingribs 14-, is curved as shown at 20 and 21, respectively, thus presentingcurved faces at opposite sides ofthe rubbing rib, the face 20 beingcurvedlongitudinally of the rib, while the face 21 curved outward upon astraight line, as shown in Fig. l. The cylinder is pro vided with aplurality of series of buckets, those of one series being extended in asingle circumferential line and in thesame direction, while those of thenext adjacent series are disposed in a similar line but in an oppositedirection, thus providing an intermediate plane portion 23 upon thecylinder which. prevents interference in the discharge or introductionof liquid by the buckets of each series. These buckets may be formed inany desired manner, for instance by slotting or punching a plate with aseries of openings 13, as shown in Fig. 5, these openings beingsubsequently embossed or swaged to form the buckets and raised flangesas shown in Fig. 6. These mechanical steps may be formed by any desiredtool or machine In the prior art, it has been customary to provide acylinder with a series of buckets formed therefrom, some of thesebuckets being disposed in one direction and the others in the oppositedirection; and the present invention comprises an inmrovement upon thearrangement and form of these buckets whereby those in one series arespaced from each other and onerge into intermediate rubbing ribsdisposed between successive buckets, while each series of buckets isseparated by a plane portion of the cylinder so as to permit a free flowof'liquid to and from the buckets, so that the series of small streamspassing from the buckets produces a continuous circulation within thecylinder and the streams do not impinge against each other. The rubbingribs provide a surface by which a scouring or rubbing action upon thearticles within the cylinder is secured whichmore quickly cleanses themand greatly increases the Working capacity of the machine. The formationof the edges of the bucket openings provides curved faces for therubbing ribs and the curving of the ends of these openings where thebucket and flange merge, prevents the collection of lint or othermaterial and also any injury to the articles within the cylinder in casethey be drawn or forced into contact with the openings as these endsavoid the sharp or wedge shaped portion liable to catch and hold the1naterial.

The invention, therefore, presents a sinr ple, efficient andeconomically constructed form of cylinder for washing and similarmachines having a series of buckets formed from the material thereof andadapted to introduce and discharge liquid from the cylinder in acontinuous series of jets which draw the articles into contact with therubbing ribs.

Having described my invention and set forth its merits What I claim anddesire to secure by Letters Patent is:

1. A cylinder for washing or similar ma chines having slots cut therein,flanges exterior of the cylinder and extending along one side and bothends of said slots and merging into buckets formed from the body of thecylinder on the other side of said previously cut slots, the part ofthecylinder between a flange andbucket being curved to produce a roundedrubbing rib.

2. In a. washing machine, a cylinder provided with a number ofcircumferentially disposed series of buckets struck up outwardly fromthe body of the cylinder in close relation to each other, the body ofthe cylinder between the buckets in a series thereof having a convexedconfori ration, the convexity of which is opposite that of the curvatureof the cylinder, whereby a curved rubbing rib is provided between eachpair of buckets in the series.

3. A cylinder for a washing or similar machine provided with a bucketformed from the body of the cylinder with the edges of the opening ofthe bucket disposed out of the plane of the body of the cylinder, theends of said openings being formed upon curved lines.

In testimony whereof I my signature in presence of two witnesses.
